Here is a flowchart I made of some basic terms. Key word: basic. There is a lot more complexity involved when discussing lgbt labels. My goal here was simply to introduce some new terms and to illustrate that things like sex, gender, gender expression, and sexual orientation are not necessarily linked.
Here is the link to the full sized chart: http://www.gliffy.com/pubdoc/3631165/L.png
Also there is a really cool diagram that I’ve seen called the genderbread person, which illustrates that these “labels” actually all lie on a spectrum of various identities.
This is totally not my image, so I have no claim to its awesomeness. I think these types of illustrations are really helpful in clearing up some common misconceptions that we tend to carry about sex and gender. Hope they helped!
